Client apparatus, server apparatus, document management system, document management method, and medium storing program thereof

ABSTRACT

A client generates a list associating a document, an operation for the document, and a user and transmits the list to a server. When an operation for the document is received from a user, the client acquires information including a document, an operation for the document, and a user and transmits the information to the server. The server receives and stores the list from the client, receives the information from the client, searches storage unit for a list including information matching the information, and transmits the list to the client. The client receives and displays the searched list.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a client apparatus and a server apparatus that manage documents used in a workflow, a document management system, a document management method, and a medium storing a program thereof.

2. Description of the Related Art

Electronic documents constitute the center of work, and there is an increased need for a system that can associate and manage the electronic documents and the work. An example of generally known solving means includes a workflow system. In the workflow system, a flow of work is defined in advance as a workflow, and documents necessary for the status of the defined workflow are attached to advance the process.

For example, as in an approval system, a workflow “create (regular employee)→scrutinize (section chief)→approve (department chief)” is created in advance. To process an authorization document, an application is attached to “create” of the flow, and approvals of the section chief and the department chief are provided to the document in “scrutinize” and “approve”, respectively.

However, there are problems that details of the user rule or the flow need to be set in advance in the workflow system and that a large amount of man-hours is necessary to use the workflow system in small-scale work. There is also a problem that the system is expensive and large-scale because a workflow engine needs to be installed to control complicated flows.

In the workflow system, documents are included in the workflow. Therefore, there is a problem that although a document can be searched from the workflow, the workflow (work) that the document is processing cannot be searched from the document.

Therefore, in a small-scale user environment, a method is often implemented, in which a document management system and a To-Do list function thereof are used to simply associate the electronic documents and the work.

In such a system, each user can provide a flag, such as a To-Do flag, to the documents on the document management system and can also describe the work content. In such a system, documents with flag can be listed and displayed by use of To-Do folders, etc.

As a result, the user can set a flag to a document that needs to be processed and can describe the work content to be processed. The user can also check, as necessary, the list of the documents that need to be processed based on the To-Do folders. Therefore, the documents and the work that requires processing for the documents can be associated.

However, there is a problem that the combination of the document management system and the To-Do list can be used only as notes of individuals, and the workflow for passing the work from person to person cannot be realized.

To solve the problems, Japanese Patent Laid-Open No. 2000-123071 proposes a system in which other users can add items to the To-Do list.

SUMMARY OF THE INVENTION

However, in the conventional technique, one system manages things in different domains: a document-based document management system and a work-based To-Do list. Therefore, the operations of the two types of domains are not coordinated, and the operation needs to be intentionally switched between operation of documents and checking of To-Do list. Thus, there is a problem that the work of the To-Do list may be overlooked when a document-based operation, which is an original usage of the document management system, is performed.

Japanese Patent Laid-Open No. 2000-123071 describes consolidated management of individual tasks and group tasks in the To-Do list. However, the difference in operations between the document operation and the To-Do list management in the document management system is not particularly considered or described.

DESCRIPTION OF THE EMBODIMENTS

Preferred embodiments of the present invention will now be described in detail with reference to the drawings. The same constituent elements are designated with the same reference numerals, and the description will not be repeated.

FIG. 1 is a block diagram showing a system configuration in the embodiments according to the present invention. The present system is constituted by a client apparatus and a server apparatus. Client software 1000 is installed on the client apparatus of the document management system. Server software 1100 is installed on the server apparatus of the document management system. The software is operated on an OS of a computer (client apparatus or server apparatus) constituted by a CPU, a RAM, a ROM, an HDD, etc.

A user interface 1001 is a user interface unit. The system receives a user operation through the user interface 1001 and transmits the user operation to a command control unit 1002.

The command control unit 1002 uses a communication control unit 1003 and a To-Do list control unit 1004 according to an operation request of the user and returns the operation result to the user interface 1001. The communication control unit 1003 communicates with the server software 1100 according to a command of the command control unit 1002.

The To-Do list control unit 1004 controls a To-Do list according to a command of the command control unit 1002.

A communication control unit 1101 communicates with the client software 1000 according to a command of the document management control unit 1102.

The document management control unit 1102 uses a database control unit 1103 according to an operation request of the client software 1000 and returns the operation result to the client software 1000 through the communication control unit 1101.

The database control unit 1103 controls a document database 1104, a To-Do list database 1105, and a user management database 1106 according to a command of the document management control unit 1102.

The document database 1104 stores document information. The To-Do list database 1105 is a To-Do list database and stores To-Do list information. The user management database 1106 is a user management database and stores user information.

FIG. 16 is a diagram showing a configuration of a general information processing apparatus used in the client apparatus or the server apparatus of the present document management system.

A computer 1600 comprises a CPU 1601. Based on a ROM for programs of a ROM 1603, a document processing program stored in an external memory 1610, etc., the CPU 1601 controls document processing including the processes of the embodiments and controls the execution of a printing process or a print control process based on the document processing. The CPU 1601 comprehensively controls the components connected to a system bus 1611.

The ROM for programs of the ROM 1603 or the external memory 1610 stores an operating system program (hereinafter, “OS”), etc., as a control program of the CPU 1601. A ROM for fonts of the ROM 1603 or the external memory 1610 stores font data, etc., used for document processing. A ROM for data of the ROM 1603 or the external memory 1610 stores various data used for document processing, etc. A RAM 1602 functions as a main memory, a work area, etc., of the CPU 1601.

A keyboard controller (KBC) 1604 controls key input from a keyboard 1608 or a pointing device not shown. A CRT controller (CRTC) 1605 controls display by a CRT display (CRT) 1609. A disk controller (DKC) 1606 controls access to the external memory 1610 by a hard disk (HD), etc., that stores various programs or applications, etc. A network interface 1607 executes a communication control process with an external device through a network.

The CPU 1601 opens various windows registered in advance based on a command instructed by a mouse cursor not shown, etc., on the CRT 1609 and executes various data processing. For example, when the user executes printing, windows related to the print setting are opened, and settings, such as print setting and print mode selection, of a print processing method for the print control apparatus can be performed.

A conventional process will be described first.

A flow of a conventional To-Do list creation process will be described with reference to FIGS. 2, 12, and 13. The user first uses a To-Do list creation instruction screen shown in FIG. 2 to select documents through the client software 1000 and instructs creation of a To-Do list for the documents. After receiving a request of the user through the user interface 1001, the client software 1000 displays a To-Do list creation screen shown in FIG. 12 to the user, the screen displaying a comment input field.

After the user inputs comments and notifies that all input is finished, the client software 1000 receives the notification through the user interface 1001. Having received the notification, the client software 1000 notifies the reception and the user who created the To-Do list to the server software 1100 through the communication control unit 1003. After receiving the notification, the server software 1100 stores the created To-Do list in the To-Do list database 1105.

The To-Do list database created in the To-Do list database 1105 includes information as shown in FIG. 13. However, the target users and the target documents may be IDs that can uniquely identify the targets.

A conventional To-Do list display method will be described with reference to FIGS. 14 and 15. The user first instructs to display the To-Do list through the user interface 1001. Receiving the user operation, the client software 1000 reports the operation execution users to the server software 1100. After receiving the operation execution users, the server software 1100 creates a To-Do list to be displayed in the document management control unit 1102.

The following process is executed in the document management control unit 1102. First, in response to the user operation, the operation execution users are acquired (step S1401). To-Do lists are then acquired one by one from the To-Do list database 1105, and the following process is executed between steps S1402 to S1405.

Whether the target users of the To-Do list are identical to the operation execution users is first checked (step S1403). If they are not identical, the next checking of To-Do list is performed. If they are identical, the process proceeds to step S1404.

If the comparison in step S1403 indicates they are identical, the To-Do list is set as a To-Do list to be displayed (step S1404). If there is one or more To-Do list in the To-Do list to be displayed after the process is executed for all To-Do lists, the list is returned to the client software 1000. If there is no list, that fact is returned to the client software 1000 (step S1406).

In the conventional technique, after receiving the display To-Do list from the server software 1100, the client software 1000 presents the list to the user as shown in FIG. 15. In the conventional technique, the user can only check the details of the To-Do list on the To-Do list displayed as in FIG. 15.

Processes of the present embodiments will now be described.

First Embodiment

A procedure of a To-Do list creation process in the present embodiment will now be described with reference to FIGS. 2, 3, 4, and 7. The steps in FIG. 7 are processed by the CPU 1601 in the client apparatus.

The user first selects documents through the client software 1000 as shown in FIG. 2 and instructs to create a To-Do list of the documents. After receiving the request of the user through the user interface 1001, the client software 1000 transmits the request to the server software 1100 through the communication control unit 1003.

Having received the request, the server software 1100 acquires a target operation list from the To-Do list database 1105 and a target user list from the user management database 1106 and returns the result to the client software 1000. After receiving the lists, the client software 1000 displays a To-Do list creation screen as shown in FIG. 3 to the user, the screen displaying a list of the target operations and the target users.

As shown in FIG. 3, a target user list and a target operation list are added in the present embodiment as compared to FIG. 12. The user selects, for example, “User A” and “User B” in “Target User List” for the documents and selects “Edit” in “Target Operation List” as a target operation of the users. An instruction for modification, etc., is described in the comment field.

After the user selects the target users and the target operations, inputs a comment, and notifies that all input is finished, the client software 1000 receives the notification through the user interface 1001. Having received the notification, the client software 1000 generates a To-Do list in the To-Do list control unit 1004. The To-Do list control unit 1004 first acquires the target users, the target operations, and the comments (step S701). The To-Do list control unit 1004 then acquires the documents as operation targets (step S702).

The documents as operation targets are combined with the target users, the target operations, and the comments to generate a To-Do list (step S703). The client software 1000 transmits the generated To-Do list to the server software 1100 through the communication control unit 1003. The process in steps S701 to S703 is an example of list generation in the present embodiment. Meanwhile, the server software 1100 stores the received To-Do list in the To-Do list database 1105.

The target operation list displays “Edit”, “Move Document”, “Copy Document”, “Delete Document”, “Print”, “Set Access Right”, “Add Tag”, etc. The To-Do list database created in the To-Do list database 1105 includes information as shown in FIG. 4. However, the target users and the target documents may be IDs that can uniquely identify the targets.

In the present embodiment, as shown in FIG. 3, the user can select target users and target operations from the lists on the To-Do list creation screen. In this way, the To-Do list can simply realize a workflow system for passing work from person to person.

The To-Do list control unit 1004 combines the documents in the To-Do list. Furthermore, as compared to FIG. 13, an item of target operation is added to the To-Do list database in the present embodiment as shown in FIG. 4. In this way, comments (To-Do) and personnel in an operation (workflow) for processing the documents can be set in association with the documents upon the creation of the To-Do list in the present embodiment. The setting can be executed in the check item as shown in FIG. 3, and the user can very simply perform the setting operation.

A To-Do list display method in the present embodiment will now be described with reference to FIGS. 5 and 6. In the present embodiment, after the To-Do list is generated according to the process shown in FIG. 7, the To-Do list is displayed on the screen of the client according to the process shown in FIG. 5 when the user performs an operation for the documents. The steps in FIG. 5 are processed by the CPU 1601 in the server apparatus.

The user first selects documents from the client software 1000 through the user interface 1001 and gives instructions for specific document operations for the documents. It is assumed here that an edit operation is selected. Having received the user operations, the client software 1000 transmits the user operations, the target documents, and the operation execution users to the server software 1100.

The server software 1100 creates a To-Do list to be displayed in the document management control unit 1102. A process as shown in FIG. 5 is executed in the document management control unit 1102. The server software 1100 first acquires the target documents, the user operations, and the operation execution users (step S501).

To-Do lists are acquired one by one from the To-Do list database 1105, and the following search process is executed in steps S502 to S507. Whether a target document of the To-Do list is identical to a target document of the user operation is determined (step S503). If they are not identical, a loop of steps S502 to S507 is repeated for the next determination of the To-Do list. On the other hand, if they are identical, the process proceeds to step S504.

Whether the target operation of the To-Do list is identical to the user operation is then determined (step S504). If they are not identical, the loop of steps S502 to S507 is repeated for the next determination of the To-Do list. On the other hand, if they are identical, the process proceeds to step S505.

Whether the target user of the To-Do list is identical to the operation execution user is then determined (step S505). If they are not identical, the loop of steps S502 to S507 is repeated for the next determination of the To-Do list. On the other hand, if they are identical, the process proceeds to step S506.

If all comparisons in the determinations of steps S503 to S505 are identical, the To-Do list is set as a To-Do list to be displayed (step S506).

After executing the process for all To-Do lists, if there is one or more To-Do list in the To-Do list to be displayed (display To-Do list), the list is transmitted to the client software 1000. If there is no list, that fact is transmitted to the client software 1000 (step S508).

Having received the display To-Do list from the server software 1100, the client software 1000 presents the list to the user as shown in FIG. 6.

In the present embodiment, the user can select whether to advance the process, check details of the To-Do list, or to cancel a desired operation on the displayed To-Do list.

For example, in FIG. 6, the user can select “To-Do 1 Related to Operation” and press a button “Check To-Do” to check details of the To-Do list (such as an instruction for modification). The user can also press a button “Continue Operation” to advance the edit operation, etc. The user can also cancel a desired operation (such as edit operation) with a button “Cancel Operation”.

As described, in the process (workflow) for editing the document, a To-Do list related to the operation is automatically displayed when the user edits the document. The user can advance the process according to, for example, the instruction described in the comment of the To-Do list. Therefore, the user does not have to treat the To-Do list in a different operation during the operation of the document management system. Furthermore, the To-Do list automatically opens in the operation of the document management system. Therefore, the leakage of the content (such as modification) that the user wants the target user to perform in the workflow can be prevented. Only the list related to the document operation is displayed in the To-Do list, and the user can efficiently advance necessary work.

A simple workflow system is realized by the To-Do list in the present embodiment. Therefore, a special configuration such as a workflow engine is not required, and a system for passing the work from person to person can be realized.

Second Embodiment

A second embodiment will now be described. In the present embodiment, even if there is a To-Do list associated with an operation similar to the operation desired by the user, that fact is notified to the user. In the present embodiment, a process for creating the To-Do list is the same as in the description of the first embodiment shown in FIG. 7.

A To-Do list display method in the present embodiment will be described with reference to FIGS. 8, 9, 10, and 11. In the present embodiment, a database (table) showing the relationship between the operations as shown in FIG. 8 is added and held in the To-Do list database 1105 of the first embodiment. As shown in FIG. 8, user operations and operations related to the user operations are associated.

The user first selects documents from the client software 1000 through the user interface 1001 and instructs specific document operations for the documents. It is assumed here that a document display operation is selected. Having received the user operation, the client software 1000 transmits the user operations, the target documents, and the operation execution users to the server software 1100.

In the server software 1100, a To-Do list to be displayed in the document management control unit 1102 is created. The document management control unit 1102 executes a process as shown in FIG. 9. The steps in FIG. 9 are processed by the CPU 1601 in the server apparatus. The server software 1100 first acquires the target documents, the user operations, and the operation execution users (step S901).

To-Do lists are acquired one by one from the To-Do list database 1105, and the following search process is executed in steps S902 to S907. Whether a target document of the To-Do list is identical to a target document of the user operation is first determined (step S903). If they are not identical, a loop of steps S902 to S907 is repeated for the next determination of the To-Do list. On the other hand, if they are identical, the process proceeds to step S904.

Whether there is an operation related to the user operation is then determined. The database (FIG. 8) showing the relationship between the operations included in the To-Do list database 1105 is referenced to determine whether there is an operation related to the user operation (step S904). If there is no operation, a loop of steps S902 to S907 is repeated for the next determination of the To-Do list. On the other hand, if there is an operation, the process proceeds to step S905. The process of step S904 is an example of a second search in the present embodiment.

Whether the target user of the To-Do list is identical to the operation execution user is then determined (step S905). If they are not identical, the loop of steps S902 to S907 is repeated for the next determination of the To-Do list. On the other hand, if they are identical, the process proceeds to step S906.

If all comparisons in the determinations of steps S904 to S906 are identical, the To-Do list is set as a To-Do list to be displayed (display To-Do list) (step S906).

After executing the process for all To-Do lists, if there is one or more To-Do list in the display To-Do list, the operation related to the list is transmitted to the client software 1000. If there is no list, that fact is transmitted to the client software 1000 (step S908).

As described, in the present embodiment, whether the target related operation (such as editing) is identical to the user operation serves as the determination condition in the display process of the To-Do list when the target user who processes an operation (workflow) including the document executes one process (such as displaying).

In step S904 shown in FIG. 9, the determination process of step S504 shown in FIG. 5 may be added to determine whether the target operation is identical to the user operation.

A To-Do list display method in the present embodiment will now be described with reference to FIG. 11. Having received the display To-Do list from the server software 1100, the client software 1000 determines whether there is a To-Do list in a related operation (step S1101). If there is no list, the operation desired by the user is executed (step S1104), and the present process ends.

FIGS. 10 and 11 are realized in step S904 as an example of the second search. In the present embodiment, FIGS. 10 and 11 illustrate an example of “second display”. The steps in FIG. 11 are processed by the CPU 1601 in the client apparatus.

On the other hand, if there is a To-Do list in a related operation, that fact and the list are presented to the user as shown in FIG. 10 (step S1102). The user can advance the process of the current operation, switch to the presented operations, or cancel the current operation on the displayed To-Do list.

For example, it is assumed that the screen shown in FIG. 10 is displayed when the user is performing a display operation. In that case, the user can advance the process (displaying) with a button “Continue Operation” shown in FIG. 10. The user can also switch the operation to a presented operation (for example, “Edit” set to To-Do 1 of Related Operation) with a “Change Operation” button. The user can also cancel the desired operation with a button “Cancel Operation”. Thus, the user can select the current user operation and operations related to the operation in the present embodiment.

If “Continue Operation” is determined in step S1103, the user performs the desired operation (step S1104), and the process ends.

If “change operation” is determined in step S1103, the user changes the desired operation to an operation associated with the To-Do list (step S1105), and the process ends.

If “Cancel Operation” is determined in step S1103, the user cancels the desired operation (step S1106), and the process ends.

As described, according to the present embodiment, when a document operation designated by the user is performed, a To-Do list of operations related to the document operation is automatically displayed. Therefore, for example, the user can advance the process according to an instruction described in a comment of the To-Do list of the designated document operation and can also advance the process according to an instruction described in a comment of the To-Do list of related operations.

In the present embodiment, FIG. 6 may be displayed as in the first embodiment if there is no operation related to the user operation and there is an identical target operation when the determination process of step S504 shown in FIG. 5 is added to step S904 shown in FIG. 9.

If both the related operation and the identical target operation exist, both FIGS. 6 and 10 may be displayed, or one screen may display the operations.
